In the light of 7/7, how would *you* handle it?
I'm in two minds about this, on the one hand, in the light of 7/7, I suspect the authorities have to take every potential threat, however ridiculous, as a potential hazard.
I can imagine the relevant authorities groaning and moaning about having to haul this guy in, but are acting under the strictest protocols - "we cannot afford another 7/7" "No matter how ridiculous the threat appears, we have to take it seriously"
The guy is an idiot for posting what he did. Some things you just *don't* joke about publicly - whether you think it stupid or not, it's obvious the authorities can't ignore a threat, no matter how innocuous it may seem...
would you want to call the relatives of the victims of another 7/7 ?
would you want to explain to the country "we thought he was just joking?" after he blows himself up in an airport?
On the other side, I think a possible jail sentence is downright ridiculous - give the guy a fine, a slap on the wrist and send him home.
